A new Pew Research analysis finds that 30 of the world’s countries (15%) belong to a unique group of nations that call for their heads of state to have a particular religious affiliation. From monarchies to republics, candidates (including descendants of royal monarchies) in these countries must belong to a specific religious group.
This list includes Lebanon, which requires its president to be a member of the Maronite Christian Church. On Wednesday, Lebanon’s parliament will make a ninth attempt since May at filling the office.
